you can only fit one plant in a rubbermaid box..... i got one and after 3 weeks...only one will fit...good luck my rubbermaid box is the sh*t....works flawless..

PS...save yourself sometime...since the rubbermaid box is so small..invest in some Female seeds....i germ 2 WL White sKunk seed on my first run with the box....it was to small for both...Both turned out male....You can check my old log...it on here somewhere.....good luck!
